Lost internet connectivity for one computer on a two computer home network
Posted on 2004-09-29
I setup a two computer network using a netgear 4 port hub coonecting both computers to a BellSouth DSL modem for internet access. This was a week ago and everything worked great until last night. The upstairs computer can't access the internet now, while the downstairs computer can. I can ping both computers and the DSL modem, I cann access the downstairs computer from the upstairs and vice versa. Everything works EXCEPT the upstairs can't access the internet. No software has been added, no changes have been made to either computer, there has been no adverse weather of any kind, no power surges... nothing. No changes at all have been made to any part of the network since initial setup when everything worked fine. Both systems use Win XP Pro w/SP2 as the OS, the NIC cards, cables and hub have all been checked out... no hardware problems. Any ideas??????
PS: the downstairs computer still can access the internet, only the one upstairs can't.
